Noods- I think Mopar was referring to the buyout offer rumor that was posted to some website right around the time of the USPTO update. It was within a day or two but to clarify I also believe I recall a big volume and price spike that fell more in line with the patent development and not the bogus buyout rumor. IIRC the buyout rumor was around 11.50 a share or something...
I think (hope) that most of the movement was due to the patent development.
